DOOR CATCH AND BUFFER.

SPECIFICATION forming part of Letters Patent N 0. 708,401, datedSeptember 2, 1902.

Application filed April 3, 1902. Serial No. 101,188. (No model.)

To (1/7/71 whont it may concern:

Be it known that we, FRENOHE. BANS-DELL and HENRY G. MUDDIMAN, citizensof the United States, residing at Manassas, in the county of PrinceWilliam and State of Virginia, have invented certainnew and usefulImprovements in Door Catches and Buffers; and We do declare thefollowing to be a full,

clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to the letters of reference marked thereon, which form a part ofthis specification.

This invention relates to devices of the class mentioned which areattachable to a door jamb or casing; audits objects are to prevent noiseand jarring when the door is being closed and to avoid rattling of thedoor after it is closed.

The accompanying drawings illustrate the invention, in which Figure 1 isan elevation of part of a doorjamb and our device in normal positionthere on; Fig. 2, a plan view in normal position; Fig. 3, a plan withthe door, fragmentarily shown, closed againstit; Fig. 4, a rearelevation; Fig. 5, a section on line 00 0c of Fig. 4; and Fig. 6, a plansimilar to Fig. 3, but with the sides of the outer and inner framespartly broken away.

Likeletters of reference denote corresponding parts in the severalviews.

The letter A indicates the outer frame of the device, having a back Aand two sides A a part of the latter being bent outwardly at a rightangle to form wings a a, which are provided with nail or screw holes aa. B is an inner frame secured to the outer frame by a pivot 19 andhaving a limited movement thereon. It has no back corresponding to thepart A of the outer frame, but its two sides B are connected to theframes angular portion, which forms the contact-faces e e.

i The plan outlines of these two frames nearly correspond, except thatthe angle A of the outer frame is approximately a right angle, while theangle of the inner frame is less than that of the outer frame. A spring0, preferably a leaf-spring fixed in the outer frame,

operates to keep the inner frame in normal position by pressure againstthe back of the face c. When the door is closed, the contact-face e ofthe inner frame is forced back by the door. The inner frame is turned onthe pivot 12, and the other face e is pressed against the edge of thedoor, which is thus securely held. On opening the door the spring 0throws the inner frame into normal position again, which is thussecurely held. The use of rubber cushions D either on the faces 2 e oron the door enhances measurably the effect of the device.

It is evident that our device may be attached to the door-casing overthe door and that a block or other projection secured on the door mayengage its faces instead of the door itself and with the same results.

We do not limit ourselves to the exactother face to engage the edge ofthe door when closed, and means to restore the inner frame to its normalposition when released from the door-pressure.

2. A door catch and buffer having an outer frame provided withattaching-wings and screw-holes therein, and having a back and twosides, an inner frame having two sides and pivotal connection with saidouter frame,

and contact'faces disposed at an angle to each other, a spring to holdthe inner frame in normal position and a cushion interposed betweenthedoor and said faces substantially as'herein specified.

In testimony whereof we afix our signa-.

tures in presence of two witnesses.
